Wireless WAN Driver not showing in device manager on Yoga 370 20JJ

Hi. I've go issues with the Sierra EM7455 Wireless WAN Driver on Yoga 370 20JJ (Windows 10). Yesterday I installed the driver on the PC. It didn't show in Device Manager. It is not listed in the network and sharing center. My first thought was BIOS settings, but they are set correctly. The SIM card is 100 % working, but that isn't the issue either. I then tryed to install the latest BIOS driver for 370's and still no luck. I am kinda stuck now, and i'm dry of ideas. Any suggestions to solve this?

Hello IT-Jogge,

Thanks for using the Lenovo forums.


Try to download the WiFi and Chipset drivers for the unit from the support page.

Make sure to reboot the unit after an update.

 

Hope this helps, let us know how you get on.

IT-Jogge,

could you provide full MTM of your laptop (it begins with 80JJ)? If it's a CTO model, send me laptop's serial number via forum's private messages service.

I've now installed both drivers for Chipset and WiFi drivers. But this didn't seem to help me any further. If you have other suggestions, let me know them. Thanks for your reply.

Unfortunately, laptop with MTM 20JJ0025MD doesn't have a wwan card factory installed:

I can't confirm clearly whether the laptop is "wwan upgradable", i.e.has wwan antennas set..

Well, that makes sense. I had my thoughts about that aswell. I opened the backcover, but wasn't able to confirm if the wwan card was installed or not. This reply helped me alot. Thank you, and happy easter.
